Description

A kind of gear pin-lift arrangement of seamless pipe expander push rod
Technical field
The utility model relates to seamless steel pipe expander production technical field, is specifically related to the gear pin-lift arrangement a kind of seamless steel pipe pipe expanding device being used for backstop and discharging push rod.
Background technology
What seamless steel pipe expander production equipment mainly utilized push rod to realize steel pipe subtracts wall and expanding object, be used for producing diameter and be greater than the steel pipe of 219mm, in order to improve expander efficiency and handled easily operation, seamless steel pipe pipe expanding device needs corresponding device to realize the backstop to expander push rod and release operation.
Summary of the invention
For the deficiencies in the prior art, the utility model aims to provide that a kind of structure is simple, the processing ease gear pin-lift arrangement being used for backstop and release push rod be arranged on push rod feeding skid that efficiency is high simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
A kind of gear pin-lift arrangement of seamless pipe expander push rod, comprise gear push rod main body and angling cylinder, gear push rod main body is fixed on push rod feeding skid, in semi-cylindrical, comprise installation portion, cambered surface wall and draw-in groove, this installation portion is arranged on semi-cylindrical gear push rod main center point, and draw-in groove is opened on its cambered surface wall of gear push rod main body, and draw-in groove is positioned at above feeding skid; Angling cylinder is fixed on the installation portion place of gear push rod main body by its revolution axle head.
Preferably, described draw-in groove comprises the first straight wall, the second straight wall and the 3rd straight wall, arc transition between the first straight wall and the second straight wall, and arc transition between the second straight wall and the 3rd straight wall and the first straight wall and the 3rd straight wall open wide outwardly.
The utility model has following beneficial effect:
The gear pin-lift arrangement of a kind of seamless pipe expander of the utility model push rod, is arranged on and push rod feeding skid is used for backstop and release push rod, has that structure is simple, the processing ease advantage that efficiency is high simultaneously.
Accompanying drawing explanation
Fig. 1 is its simple structure schematic diagram of gear pin-lift arrangement of a kind of seamless pipe expander of the utility model push rod.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the technological thought that the utility model is claimed so that clearer.
The gear pin-lift arrangement of a kind of seamless pipe expander of the utility model push rod as shown in Figure 1, comprise and be fixed on gear push rod main body 3 on push rod feeding skid 1 and angling cylinder 4, described gear push rod main body 3 one-tenth semi-cylindricals, comprise installation portion 30, cambered surface wall 31 and draw-in groove 32, this installation portion 30 is arranged on semi-cylindrical gear push rod main body 3 central point, draw-in groove 32 is opened on its cambered surface wall 31 of gear push rod main body 3, and draw-in groove 32 is positioned at above feeding skid 1; Wherein said draw-in groove 32 blocks push rod 2 for backstop, comprise the first straight wall 322 of straight wall 321, second and the 3rd straight wall 323, arc transition between first straight wall 321 and the second straight wall 322, arc transition between the second straight wall 322 and the 3rd straight wall 323 and the first straight wall 321 and the 3rd straight wall 323 open wide outwardly; Angling cylinder 4 is fixed on installation portion 30 place of gear push rod main body 3 by its revolution axle head, and described angling cylinder 4 is used for driving gear push rod main body 3 to swing certain angle, realizes push rod 2 to discharge.
Operation principle of the present utility model is: push rod 2 rolls the gear push rod main body 3 to gear pin-lift arrangement from feeding skid 1, and block push rod 2 by the draw-in groove 32 in gear push rod main body 3, angling cylinder 4 drives gear push rod main body 3 to swing, gear push rod main body 3 rotates around its installation portion 30 central shaft, until push rod 2 departs from from the draw-in groove 32 gear push rod main body 3, realize the release of push rod 2.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
